I am getting this error on the current version (6.0) when trying to invoke Save method using MemoryStream:
{"Path cannot be null.\r\nParameter name: path"}
Here is the code:
certStream.Seek(0,
SeekOrigin.Begin);
//PdfFileSignature pdfSign = new PdfFileSignature(fNameIn, fNameOut);
PdfFileSignature pdfSign = new PdfFileSignature();
ms.Seek(0,
SeekOrigin.Begin);
pdfSign.BindPdf(ms);
ms.Dispose();
System.Drawing.
Rectangle rect = new System.Drawing.Rectangle(480, 523, 300, 35);
pdfSign.CertificationLevel =
PdfFileSignature.CertifiedNoChangeAllowed;
Pkcs1Signature signature = new Pkcs1Signature(certStream, encPwd); // PKCS#1 or
signature.Reason = coSignerInfo;
signature.Name = Context.User.Identity.Name;
signature.Location =
"";
signature.Contact = Context.User.Identity.Name;
pdfSign.Sign(
string.Format("CoSign{0}", (i + 1).ToString()), signature);
ms =
new MemoryStream();
pdfSign.Save((
MemoryStream)ms);
Here is the stack trace:

This was reported previously and supposedly fixed. ?????
